Judged by his own high standards, Angel Di Maria didn't have his best game against Switzerland in the last 16.
He gave the ball away again and again, and when he found himself in dangerous positions, he tried things that didn't come off.
But at the end of extra time, it was all irrelevant. The records will show that Di Maria scored the winning goal. It will probably be remembered that he did it with a crisp, first-time finish after Lionel Messi had run at the Swiss defence.
It was well-earned after Di Maria's tireless running in extra time when most of the other 21 players had long since stopped.
Alejandro Sabella told FIFA.com he was happy with the win over Switzerland but insists they'll have to improve to beat Belgium:
We deserved the win, but the ideal thing would have been to have got the job done in normal time. It goes without saying that winning is the most important thing and the only thing that really matters. ...
... Apart from the odd lapse in concentration here and there, I think the team played well. ...
... I’d like to congratulate my players on their great performance, though there are some areas where we need to improve.
Argentina will need another match-winner against Belgium in the quarter-finals. And Di Maria is one of their number with that ability.
